Thanks for the infos Klojum and HiassofT .
If a "like" has been removed, then it's a bad sign to me, and I'm interested to know the cause. I didn't know it can be removed.
Collecting a max. amount of "likes" is not my goal. However, getting positive feedback definitely is a goal, and a sign of successful support.
PS: I did the experiment, and hit the "like" button twice, which removes the "like". Maybe the user did that to like me even more. ![]()
The "like" button is partualy misleading, because the thumb is still up after hitting the button for the first time. Actually it should be a "thumb down" button when it results in removing the "like".
